在Google Cloud上将图像转换为原始格式

贡献者

用于部署新实例、升级或正在现有映像中使用的映像将通过与客户端共享 "NetApp 支持站点 (NSS)"。签名摘要和证书可通过NSS门户下载。确保您下载的是与NetApp支持共享的映像对应的正确版本的摘要和证书。例如、9.13.0映像将具有9.13.0签名的摘要和证书、可在NSS上使用。

为什么需要执行此步骤？

无法直接下载Google Cloud中的映像。要根据签名摘要和证书验证映像、您需要有一种机制来比较这两个文件并下载映像。要执行此操作、您必须将映像导出/转换为disk.raw格式、并将结果保存在Google Cloud的存储分段中。disk.raw文件会在该过程中进行tarbred和gzipped。

用户/服务帐户需要具有执行以下操作的权限：

  • 访问Google存储分段

  • 写入Google Storage bucket

  • 创建云构建作业(在导出过程中使用)

  • 访问所需映像

  • 创建导出映像任务

要验证映像、必须先将其转换为disk.raw格式、然后再下载。

使用Google Cloud命令行导出Google Cloud映像

将映像导出到云存储的首选方法是使用 "gcloud compute images export命令"。此命令将获取提供的映像、并将其转换为disk.raw文件、该文件会进行tarred和gzipped。生成的文件将保存在目标URL处、然后可下载以进行验证。

要执行此操作、用户/帐户必须具有访问和写入所需存储分段、导出映像以及云构建(供Google用于导出映像)的权限。

使用gcloud导出Google Cloud映像

单击以显示脚本 
$ gcloud compute images export \
    --destination-uri DESTINATION_URI \
    --image IMAGE_NAME

# For our example:
$ gcloud compute images export \
    --destination-uri gs://vsa-dev-bucket1/example-user-exportimage-gcp-demo \
    --image example-user-20230120115139


## DEMO ##
# Step 1 - Optional: Checking access and listing objects in the destination bucket
$ gsutil ls gs://example-user-export-image-bucket/

# Step 2 - Exporting the desired image to the bucket
$ gcloud compute images export --image example-user-export-image-demo --destination-uri gs://example-user-export-image-bucket/export-demo.tar.gz
